thanks for the help you seem to be on top of these ford problems.
i have a 2000 f150 xlt with electrical problems.
i have replaced the interior lamp relay #1 left side fuse box inside cab
replaced battery saver relay #2 left side fuse box inside cab
replaced the one touch down window relay #3
replaced acc delay relay #4 inside cab
50 amp junction blockbattery feed fuse replaced
replaced the wiper relay in the power distribution box relay 202
my windows and wipers and dome light and brake lights still do not work
the question i have is relay 1 2 3 4 on the left side fuse box in cab what
pins should have voltage on them.
power saver relay has 11.54 volts on pin #1 and 11.47 on pin #3
any help would be appreciated
thanks

 

Did all 4 problems happen at the same time, or at different times ?

Are there any other symptoms, like the Blower motor not working, or still running after the key is turned to the off position.

Have you had a lot of rain / melting snow in your area since the problems started ?

With the numbers of 1-2-3-4-5, the layout is :
1 = power to relay coil
2 = Ground to Relay Coil
3 = Common Power in
4 = ( if used ) is the Normally closed contacts to pin #3
5 = Normally open contacts to Pin #3.

With the power saver relay having power on Pin #1, Can you check Pin #2; the ground on the Battery saver relay is switched via the timer circuit on the GEM.

If you pull the triangle shaped trim panel that the power window switches are on, and check the Light Blue with a black stripe wire on the power window switch controller, with the key in the Accy or Run position, do you have ~ 12 V DC ? This is with the relays installed in the correct places.

If you want to bypass the Accy Delay or Battery saver relay, use male terminal spade connectors ( filled down slightly or get the small ones to fit the relay socket, standard full size are too big ) and create a jumper from the Pin #3 to Pin #5, this will bypass the Relay, and the timer circuit in the GEM, and should power the Power windows at all times.
If you jumper both relays, do the items work correctly ?

Just trying to get an idea if we are looking at a Relay or other electrical problem, or if you have a wet GEM problem.

If you have a window leak, it would show as damp carpeting ( most of the time ) at the edge of the carpet about in line ( make that up on the firewall ) with the parking brake / interior fuse panel.

Don't want to start a panic either way, just want some diag info, before jumping into some items.

Thanks, let us know what you come up with.

 

thanks sccully i,m in over my head on this electrical stuff so i just going to take it to a dealer thanks for trying to help. i tried by passing the relay on pin #3 to #5 still windows will not work have no voltage on light blue wire in triangle panel at window switches its electrical i beleive because dome light windows wipers brake lights all quit working at the same time. my blower and a/c heater all still work turn signals work
